2 MX280001A Vision Software Introduction Spectrum monitoring systems facilitate the identification and removal of interference signals that degrade network capacity. By monitoring spectrum on a continual basis, problem signals can be identified as they occur in real time. Patterns of unwanted signal activity can also be examined, providing an efficient way to characterize and locate the source of the interference problem. In addition to interference detection, spectrum monitoring is also used to characterize spectrum occupancy. Government regulators and operators are often interested in determining the usage rate for various frequency bands. Monitoring these frequencies provides the information needed to optimize spectrum for maximum utilization. Spectrum can be re-purposed for other applications or multiplexed with other signals using cognitive radio techniques. Spectrum Monitor Spectrum monitoring also serves to enforce compliance with government regulations. Police, fire fighters, air traffic control, military and emergency services must all have access to communications free of impediments and distortion. Compliance with spectrum regulations is often enforced by spectrum monitoring. Figure 1 shows spectrum monitors surrounding a prison facility, looking for illegal transmissions.

Using multiple hardware probes covering a wide geographical area, Vision presents a comprehensive picture of spectral activity to assist users in monitoring the spectrum for unusual activity. Figure 2 shows a typical signal monitoring system with Anritsu spectrum monitors positioned for maximum coverage.

3 Vision software facilitates a variety of applications used for spectrum monitoring systems. One important application includes determining the presence of interferers in a network which can degrade communications services. Cellular operators in particular are vulnerable to such interference that manifests itself in slower data rates and dropped calls. In most cases, network performance is compromised on the uplink frequency bands (communication from the mobile unit to the base station). However, network quality of service can also be impacted by interference on the downlink channels. This type of interference can be prevalent at the cell periphery where the power levels of the interference signals approximate those transmitted by the base station itself. Another important application for Vision software is the detection of illegal or unlicensed broadcast signals. Illegal broadcasters may set up AM/FM, cellular or other types of transmissions which must be identified and ultimately located. By using spectrum monitors, unlicensed broadcasts can be tracked, processed and stored in a database for further examination and potential use in legal proceedings. See figures 3 and 4 for important spectrum monitoring applications. Other applications include the following: Inform spectrum policy accumulate historical spectrum data to determine percent time of occupancy Monitor jails/prisons for unauthorized transmissions Monitor borders, airports, nuclear facilities and other sensitive areas Railroads monitor spectrum for potential interference of positive train control (PTC) signals Satellite reception interference detection Interference monitoring at large venues such as stadiums, malls, etc White space monitoring Indoor monitoring (board rooms, embassies and other sensitive facilities). See figure 5. Figure 3: Stadium monitoring Figure 4: Airport frequency monitoring Figure 5: Indoor transmissions detection 3

4 Vision Software How it Works Vision is an optional software program which runs on a PC using the Windows operating system (Windows 7 or 8). This software provides control and automation capabilities when used with Anritsu s spectrum monitor hardware. Vision is composed of two components responsible for monitoring and geo-locating interference signals, called Vision Monitor and Vision Locate respectively. Additionally, a High-Speed Port Scanner is available for rapidly switching between spectrum monitor RF In ports and scanning individual frequency channels. The High-Speed Port Scanner also enables the user to view multiple traces on a display monitor with rapid refresh rates. Each performs a wide range of spectrum monitoring and control applications designed to mitigate interference problems and detect unusual signal activity. A summary of each Vision software product is presented below. Vision Monitor The Vision Monitor program is the visible user interface for monitoring remote spectrum activity. It provides a listing of all hardware monitors in the system along with a graphic overview of system health. A screenshot of the main user interface for Vision Monitor is shown in figure 6. Figure 6: Vision monitor screen Shown here is a listing of the deployed monitors, with the ability to view both real-time and historic measurement trace and spectrogram data. 4

5 Vision Monitor performs a wide range of spectrum monitoring duties. These functions include: Measurement acquisition Data storage Threshold setting/alarm generation Reporting Users can set up the Vision program to take automatic measurements for all spectrum monitors. The measurements are in turn uploaded into a database for further review. The database is updated with new data, while old information is periodically purged according to user settings. Functions are also available for archiving, copying and compressing the database. See figure 7 for illustration. Figure 7: Vision Monitor measurement and database control With Vision Monitor, the user can set up limit lines for triggering alarms, view spectrum history and change measurement parameters of individual or groups of spectrum monitor probes. The program makes heavy use of intuitive graphics to indicate the presence of interference or other signals of interest. Additionally, searches both in real-time and over history can be made to indicate patterns of interference. In some cases, interference may only occur at certain times of the day or certain days of the week. It is important to be able to capture the signal, identify the pattern and subsequently hunt for the signal location at the appropriate times. In addition to trace data, spectrograms can be viewed to indicate changes in frequency over time for suspicious signals. For each remote monitor, Vision Monitor is capable of collecting data from as many as 24 input RF ports. This can be ideal for cellular systems with multiple sectors and multiple frequencies per sector. Figure 8 shows a screen shot of the user interface with multiple monitors overlayed on a map. Both GoogleMaps and OpenStreetMap are available. Using this map, alarm threshold violations can be easily seen with color changes on the probe indicating a frequency threshold violation at that site. If needed, automated alerts can be sent to any address provided. These alerts can be ed in real-time or sent as summary reports on a daily or weekly basis. These reports are a great tool for provide a snap shot of the network s health and provide time-stamped indications of when a suspicious signal might be present. Figure 8: Monitor positions overlaid on map 5

6 Vision Locate Vision Locate is an optional program used with Vision Monitor. Once an interferer or suspected illegal signal is identified, a geo-location algorithm is employed to fix the approximate position of the signal. This enables the user to narrow down the signal location, minimizing the time and expense for pin-pointing its position. A sample map is shown in figure 9 showing the suspected interference position using Power of Arrival (POA). In this window, the probe locations are indicated by the red squares. The interference position is identified by the concentric circles. Figure 9. Geo-location of signal on map overlay For interference that may have occurred in the past, users can also use historical data for positioning the signal of interest when Power of Arrival geo-location is used. A search can be done for alarm violations that occurred at any of the spectrum monitor probes in the network. Using three probes in the vicinity, the interference position can be geo-located. Three types of geo-positioning algorithms can be used to locate signals of interest. The Power of Arrival (POA) algorithm is used to position the interference signal when low bandwidth or non-modulated transmission are to be located. A second positioning technique is available called Time Difference of Arrival (TDOA). TDOA uses the time that a given signal arrives at each receiver. Based on the time differences measured, a calculation is made for the interference position. In general, TDOA offers superior results to POA; however, TDOA cannot be used for CW and other types of non-modulated signals. For each of these types of measurements, three or more probes must be in the vicinity to detect the signal of interest in order to correctly triangulate the position. A third type of geo-positioning available is Angle of Arrival (AoA). Angle of Arrival (AoA) provides bearing information for the position of a transmitted signal. One advantage of AoA vs TDOA/POA is that only one location is needed into order to perform geo-location. Both TDOA and POA required three positions situation in a triangle format. However, AoA only provides bearing information, ie the signal of interest lies somewhere along a trajectory line from the position of the AoA monitor to the interference signal s position. Directional antennas are used by the AoA algorithm to computer bearing lines. Power is automatically measured at each antenna port, where calculations are made based on received signal strength. 6

7 High-Speed Port Scanner The High-Speed Port Scanner scans multiple input RF In ports and multiple frequency channels measured with Anritsu Spectrum Monitors. Although the High-Speed Port Scanner works well in scanning individual frequency channels on a given RF-IN port, Option 407 is uniquely capable of quickly scanning multiple RF inputs on Anritsu s line of spectrum monitoring products. The MS27103A (either the standard 12-port RF IN design or the optional 24-port version) in particular is the perfect match for the Scanner where measurement speed is critical. The High-Speed Port Scanner can also be used with the (2-port option) and the MS27100A when equipped with the 4-port switch accessory. A key feature of the scanner is the multi-trace viewer (see Figure 10). A large number of traces can be viewed simultaneously in a single display monitor. The number of traces can be be viewed is limited only by the size and resolution of the display monitor used. Refresh rates for scanning 12 RF IN ports are typically less than one second. When scanning multiple spectrum monitor units, a multi-threading process is used. This keeps the display refresh rates under one second even when multiple spectrum monitors are used. However, rates seen are dependent on sweep settings (RBW/VBW) in the unit and the network used. A slow network for transmitting the measurements back to the monitor could delay refresh rates in the display. For the traces shown in the display monitor, marker and delta-marker functions are available for the spectrum traces. Each trace display also allows limit lines to be used to indicate alarm situations. Both Upper Limit and Lower Limit lines are available. Lower Limit line are applicable for detecting the absence of signals in a given channel bandwidth. When an alarm situation is present, the trace on the monitor is colored red. To assist users in identifying individual spectrum plots, host names and descriptions can be used. Additionally, individual parameter settings (RBW/VBW, Ref Level, use of preamplifier, etc.) can be selected. Figure 10. High-Speed Port Scanner Multi-Trace Display 7

8 Other features included with the High-Speed Port Scanner are shown below. See Figure 11 for window showing various options available. Save-on-Event users have the option to continuously save all measurements or only the measurements when limit line violations occur. Save Measurements to Spreadsheet all measurement data can be save in spreadsheet format (CSV) using either comma, semi-colon or tab delimiter formats GPS Location a selection is available to save GPS date/time/position coordinates as measurements are scanned. This feature is particularly helpful when measurements are taken in a mobile environment. Save sweep traces in an output file. Scan on System Startup an option exists to begin saving immediately when a PC/laptop is connected to a powered spectrum monitor Re-use Configuration Parameters the last configuration file (channel/port settings, measurement parameters) can be automatically loaded when the application is started Set Individual File Sizes set the maximum file size to be used for measurement storage before a new file is created Memory Storage Settings set the minimum free space allowed before old files are deleted to make room for new measurements Statistics show numbers of threshold violations, measurement count and pass rates Channel Power display channel power on screen Note that both Channel Power and Occupied Bandwidth are automatically saved in the CSV file. Figure 11. Options and Settings Windows 8

9 Remote File Viewer The File Viewer is a free utility included with the Vision software download. As part of the Vision installation, the FileViewer.exe program is placed in Vision s installation directory. Spectrum channel measurements saved as part of the High-Speed Port Scanner option can be viewed with the File Viewer. See Figure 12 for the File Viewer display. A spectrogram is available to display measurements as a function of frequency and time. Channel Power for each trace is displayed at the bottom right-hand corner of the trace display. Files saved either on a remote PC/laptop, in the spectrum monitor s flash memory or on a USB stick attached to the monitor can easily be retrieved and displayed on the viewer. In addition, the following display features are available to the user. Marker and Delta-Marker functions MAX or MIN Hold for all traces accumulated Figure 12. File Viewer Utility Average Trace Display averages over all traces accumulated and display one average All Trace Display show on one screen plot all traces measured (see Figure 13 for illustration) Video Playback automatic playback of traces with start, stop, slower, faster, play from beginning and play from current time position features The Remote File Viewer is included with the Vision installation and is free of charge.

10 Customer Upgrades Customers wanting to upgrade their Vision software with the High-Speed Port Scanner must load firmware version V or higher. The High-Speed Port Scanner is freely downloadable from the Anritsu website. However, it will only work with Anritsu spectrum monitors where a purchase of the Scanner option has been made. 3D Spectrogram Used with the File Viewer available for viewing.rsm or.csm measurement files, the 3D spectrogram enables user to view measurements as a function of both time and frequency. Figure 14 below shows and example of the 3D spectrogram display. Figure 14. File Viewer 3D Spectrogram Spectrum Occupancy (Option 485, prerequisite Option 400) Given the exponentially increasing cost of spectrum, government regulators are interested in surveying various frequency channels to determine how much a given spectrum is utilized. Underutilized frequencies could then be repurposed for other applications. An additional application for spectrum occupancy measurements is cognitive radio. Using various cognitive radio algorithms, multiple applications can be multiplexed in time for a given range of spectrum. Anritsu s spectrum occupancy implementation allows users to set power threshold levels to determine whether a given frequency channel is to be considered occupied. In this way, noise and very low-level signals can be eliminated from the analysis. Occupancy reports can also be generated for all frequency bands measured. Figure 15 (next page) shows and example of an occupancy measurement in the FM radio band. 10

11 Figure 15. Spectrum Occupancy Display (Requires option 400) Signal Broadcast Identification (Requires Option 400) When hunting interference signals, it can be helpful to have real-time information for what type of signal is authorized to be in a given channel. Regulators monitoring their frequency bands also desire to view what signals are present and whether the transmissions fall within the bandwidth allocated to a particular vendor. Anritsu s Signal Broadcast Identification feature is designed to meet these needs. Using publically available data, users can import this information so that it is readily available once the spectrum is viewed. Whatever information that is available from the government regulator (or other agency involved with broadcast licensing) can be used. Broadcast information generally supplied include the following: Identity of broadcaster GPS Coordinates of broadcaster s transmitter position Frequency band in which a broadcaster is allowed to transmit Power level authorized for the transmission Type of signal broadcast (commercial radio, public safety, cellular, etc) It should be noted that not all country s regulators supply this information and the types of information provided on the authorized broadcaster may vary. See Figure 16 (next page) for an example illustration of the broadcast identification feature. 11

12 Broadcaster information can be imported into Vision Monitor (option 400) via a spreadsheet (CSV format) and overlaid on the trace display. Additionally, users can plot the positions of all the transmitters on a map. Users can simply mouse-over an icon on the map to see a pop-up window showing all information available on that transmitter. In addition to broadcaster information supplied by the regulator, users may want to plot and identify other positions. For example, a cellular operator may want to identify the positions and frequencies of all their BTS transceiver equipment. This information is often considered proprietary and would be used only within the operator s system. Interference hunters working for the operator could use this information to know their proximity to BTS equipment to prevent over-powering their receivers. AM/FM Demodulation (Option 479) Figure 16. Signal Broadcaster Identification AM/FM is offered as a stand-alone option, which can be downloaded with the Vision software installation package available on Anritsu s website. The AM/FM option provides analysis information included AM modulation quality and FM deviation metrics. The AM/FM demodulation option also enables the user to remotely capture AM/FM signals and listen to the signals via their PA/laptop. The AM/FM signals cal also be saved as WAV or MP3 files to be played at a later time. See Figure 17 for illustration. Figure 17. AM/FM Display for Measurements and Streaming 12

13 FM deviation graphs can also be shown. The graphs are available via the RSM/Vision API only and are not included in the stand-alone application. See Figure 18 for illustration. The AM/FM demodulation option is offered only in API format for system integrators and other customers. Typical specifications for AM and FM measurements are shown here: FM Deviation (Up to 75 KHz, 5% Accuracy), Input Level > 90 dbm AM Modulation (0 to 100% Depth, 5% Accuracy), Input Level > 90 dbm Coverage Mapping (Option 486, prerequisite Option 407) Option 486 provides wireless service providers, public safety users, land mobile radio operators and government regulators with the ability to map signal information over any given outdoor geographic area. The Coverage Mapping tool is offered with the following features: Ability to scan over multiple frequency channels Measurements can be taken based on RSSI, Channel Power or Occupied Bandwidth GoogleMaps and OpenStreetMap are supported The color scale used for mapping can be changed to match the dynamic range of signals measured Measurements can be imported into Google Earth for further display and analysis See Figure 19 for an example display of the Coverage Mapping option.
